First let's see where the micro switch in the water heater is, turn on the water heater, at the bottom of the middle of the water heater, you can disassemble the outer shell of the water heater, and then turn on the water inlet switch of the water heater, at this time, you can see the pull tab inside will move. Next to it is the micro switch.
How to check the model of the micro switch in my water heater? When we find the micro switch, there will be some numbers on it, which generally represent the current parameters.
The micro switch in the water heaterThe parameters are generally:
Electrical life: 10000 times
Contact resistance: 500 mΩ MAX.
Insulation resistance: 100 MΩ MIN.
Operating temperature: -25℃~85℃
Mechanical life: 1 million times

What water heater microswitches won't work? At this time, we can find the micro switch in the water heater according to the above method. You can first check whether there is a problem with the conduction of the micro switch, check whether the switch can be turned on normally when pressed, and what is the contact resistance. Generally, a good switch has a good contact resistance. Only a few tens of milliohms, too large a resistance may also affect normal ignition.
The role of the water heater micro switch:
1. The micro switch is a quick switch actuated by pressure, also called a sensitive switch.
2. Its working principle is: the external mechanical force acts on the action reed through the transmission element (press pin, button, lever, roller, etc.), and after the energy is accumulated to the critical point, an instantaneous action is generated, so that the end of the action reed The moving contact and the fixed contact are quickly connected or disconnected.
3, The micro switch of the water heater controls the start of the machine controller and controls the ignition. When the water pressure reaches a certain level, the diaphragm inside will pass the transmission Open the micro switch on the shaft to make the water heater ignite. If the micro switch fails, the machine will not be able to ignite.
As you can see, the usefulness of water heaters in life is very important. Just a micro switch inside will affect the operation of the entire water heater, so when the above problems occur, we will not be in a hurry.
